I was not suggesting that you concern yourself with any "keep-out" functionality at this stage; in my previous message, I was submitting my assessmentof such functionality in response to others referring to it (in yet earlier messages in this thread).

I agree that another three layers could be implemented without making extensive changes to the software -- and as such, none of those layers should beimplemented without extensive discussion beforehand. IMO, an advantage of using two of those layers to implement a pair of assembly layers is that such layers would be "paired" to one another (in the same way as the Adhesive, Silkscreen, Solder Paste, Solder Mask, and external copper layers), whereas the eco1 and eco2 layers are *not* similarly paired to one another. (However I would still advocate discussing that matter comprehensively before actually implementing it.)

See my most recent previous message, in which I referred to a ZIP file which I have recently uploaded to the Files page on this mailing list. I can't give any guarantees at this stage, but I will attempt to find some time to give some thought as to how the usage status of each layer (in KiCad) couldbe calculated and subsequently displayed.

You have just confirmed what I envisaged you had in mind when you referred to layer sets previously. I fully agree that it is painful to change the visilibity of layers using the currently provided dialogs.
(Yet earlier messages to this thread snipped.)
